This model is very efficient in solution and is most commonly used in crash simulations. It is similar to the multilinear isotropic hardening behavior. Stress-strain behavior is defined with a load curve of effective true stress versus effective plastic true strain. Failure strain can be input for which elements will be eliminated. Yield surface can be scaled for strain rate dependence by the Cowper-Symonds model.

This material behavior is written as *MAT_ PIECEWISE_LINEAR_PLASTICITY , where the parameter lcss is the curve id of the effective stress versus plastic strain.
